Petter, Glendale, Califi, assignor toYStandard Paper Box Corporation, Los Angeles, Calif., a corporation of Delaware 1 Application August 17, 1953, Serial No. 374,767 1 Claim; Cl. 229-485 Further objects comprise the provision of a carton of the type mentioned which affords both isolation and protection for the individual articles packaged, and the provision of a package which presents the articles for especially attractive display to the customer.

The invention will be best understood by referring immediately to the following detailed description of a present illustrative embodiment, reference being had to the accompanying drawings, in which:

Fig. 1 is a blank from which the carton is formed;

Fig. 2 is a perspective view showing a first step in erecting the carton from the blank of Fig. 1;

Fig. 3 is a perspective view showing a second step in erecting the carton;

Fig. 4 is a perspective view of the fully erected carton, looking toward its bottom and with its rearward side up;

Fig. 5 is another perspective view of the completed carton, looking toward its front, and with its top side uppermost;

Fig. 6 is a cross-section taken in accordance with the arrows 6-6 of Fig. 4; and

Fig. 7 is a fragmentary elevational view takenin accordance with the arrows 7-7 of Fig. 6.

In the drawings, the package is designated generally by the reference numeral 10, and has integrally joined top, front side and bottom walls or panels 11, 12, and 13, respectively. Integrally joined with the rearward edge of top panel 11 is a rearward wall member 14, having a sawtooth lower edge 15, from which transverse partitions 16 extend across the interior of the box to define the multiple cells 17. These partitions 16 are connected at the opposite side of the box to an attachment panel 18, which is secured in any suitable way, as by gluing, cellophane adhesive tape, or, as here shown, a locking tongue 19, to bottom panel 13. To the rearward edge of bottom panel 19 is connected a closure panel 21 optionally formed with hooks 22 adapted to engage under the partitions 16 to lock the carton closed.

The top and front side panels are formed with display windows 22, covered with transparent sheeting 23.

The carton is erected from the blank shown in Fig. 1 at a. It will be seen that this blank is generally rectangular in shape, and comprises the aforementioned integrally joined panels 11, 12, 13, 18, and 21, together with a panel 14a made up of wall portion 14 and partitions 16, said panels being separated by score lines as shown (indicated by dot-dash lines) for ready bending.

The panel 18 and the partition portions 16 of panel ICC 14:: are offset somewhat from the panels 11, 12, 13, and 21, and swing into alinement with said panels as the carton is erected, as will presently appear (Fig. 2). This partition forming construction is generally similar to those disclosed in my prior Patents Nos. 2,103,382 and 2,639,079, and its details need not be further described.

The partitions 16 are separated from the wall portion 14 by making a plurality of generally parallel, inclined slits 25 in the panel 14a, extending from the score line 26 between panels 14a and 18 about two-thirds or a little greater toward the score line 27 between panels 14 and 11, and by extending these slits, as at 28,'along the score line 26. The slit extensions 28 terminate short of the intersection of the next slit 25 with the score line 26, and score lines 29 extend from the ends of the slit extensions 28 at right angles to the score line 26 across the partitions 16 formed by slits 25, so as to form small triangular attachment tabs 30 between the partitions and the panel 18. Score lines 31 extend from the extremities of slits 16 remote from score line 26 at right angles to the latter to intersect the adjacent slits 25.

To erect the carton 10 from the blank 10a, the attach ment panel 18 may be swung up as indicated by the arrow in Fig. 2, the score lines 29 and 31 forming hinges for the partitions, and the panel 18 moving parallel to the panels 11, 12, etc. until alined with and spaced from the latter as shown in Fig. 2. It will be seen that the partitions 16 are turned through from the wall portion 14 and also from the panel 18.

The wall 14 is then bent through 90 on score line 27 relative to top panel 11, and the latter is bent through 90 on score line 34 relative to wall 14, so that attachment panel 18 engages bottom wall 13, as shown in Fig. 3. The panel 18 may be secured to bottom wall in any desired manner, as by gluing, adhesive tape, or, as here shown, by means of a conventional locking tongue 19 engaging suitable slits 35 and 36 in bottom wall 13.

The carton is then bent through 90 on score line 37, bringing the secured-together attachment panel 18 and bottom wall 18 into engagement with the edges 38 of partitions 16, and the panel 27 is bent on score line 39 and its hooks 22 inserted inside the wall 14 and engaged under the partitions 16 (Figs. 6 and 7) to lock the carton in closed position. The hooked panel 27 is of a type fully disclosed in my aforementioned Patent No. 2,639,079, and need not be further described herein. Optionally, a lesser number of the hooks 22 may be used, saving time in closing the carton. As an alternative, the hooks 22-may be omitted, the closure flap being simply laid fiat over the wall member 14, and either glued there to, or fastened thereto by strips of adhesive cellophane tape, or the like.

The complete erected package, positioned properly for viewing by the potential customer, is seen in Fig. 5. It

I will be evident that articles placed in the cells 17 are attractively and fully displayed through the windows formed in the top and front walls. The package is inexpensive to manufacture, economical of paper stock, simple, requires no gluing, is adequately strong, and affords suitable protection for the articles contained therein. For shipment in un-erected state, the blank is conveniently folded over once on the score line 34, giving a flat compact shape.

For convenience of description, the various panels are referred to herein and in the claims as top, bottom, front side, etc., but it will be understood that this is for reference purposes only, and constitutes no limitation on the invention, since the completed package may obviously be used in any position. With the windows as here described, the front side, for example, may become the top, and the top become the front side.

Various modifications coming within the scope of the broad invention will occur to those skilled in the art,

and the invention is accordingly limited only in accordance with appended claim.

I claim:

A multiple cell single cell-row carton comprising: a closure panel, a second panel integral with and bent at right angles from an edge of said closure panel, a third panel integral with and bent at right angles from the opposite edge of said second panel, a fourth panel integral with and bent at right angles from the opposite edge of said third panel, a wall member bent at right angles from the opposite edge of said fourth panel, said wall member having an opposite edge of saw-tooth contour comprising edge portions at substantially right angles to the direction of said panels joined by parallel inclined edge portions,

parallel transverse partitions integrally joined to said F.)

right angle edge portions at one end, and an attachment panel to which said partitions are'jo'ined at their opposite ends, said attachment panel: being engageable with and secured to said second panel, and said closure panel being cngageable with and adapted to be secured against said wall member.
